Title: Fixing method of battery
Inventor: ISHIZAKA HAJIME
IPC: H01M2/10
Filed: 1984-12-28
Abstract: PURPOSE:To prevent shortcircuit between terminals by covering one of positive and negative terminals of battery with an insulation member then inserting both terminals into a printedboard thereafter passing through a solder tank and removing the insulation member to solder that terminal. CONSTITUTION:A tube 4 made of thermosetting resin having one closed end is applied over one of the positive or negative electrode terminal 2, 3 projected from the battery body 1. Then both terminals 2, 3 are passed through a hole 7 in a printedboard 5 and passed through a solder tank as it is to solder only the terminal 3 having no tube 4 to the conductive pattern 6. Thereafter, the tube 4 is removed to solder the terminal 2 to the conductive pattern 6 then fix to the printedboard 5 of battery 1.

Title: Transmission type liquid crystal display device
Inventor: KOMA TOKUO
IPC: G02F1/1337
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To shorten a response time by specifying the relation between the refractive index anisotropy of liquid crystals used as the liquid crystals of a liquid crystal layer and a cell gap which is the distance between display electrodes and a counter electrode. SOLUTION: This device is so constituted that the refractive index anisotropy Δn of the liquid crystals used as the liquid crystals of the liquid crystal layer 40 and the cell gap d[μm] which is the distance between the display electrodes 19 and the counter electrode 32 satisfies Δn.d<-0.033.d+0.88. In such a case the product Δnd of the refractive index anisotropy Δn of the liquid crystal and the cell gap (d) is called retardation. As the product Δnd is smaller, the larger driving voltage range may be taken in order to obtain the same transmittance. The response speed is higher as this driving voltage is larger and, therefore, the smaller product Δnd is more preferable. Further, the response speed is slower as the cell gap (d) is larger and is faster as the cell gap is smaller.

Title: Method for controlling plate thickness of strip metal in reciprocating rolling mill
Inventor: SATAKE YOSHIHIRO
IPC: B21B37/18
Filed: 1993-11-09
Abstract: PURPOSE:To prevent troubles such as shape change, drawing and so forth by setting upper and lower threshold values to a rolling load at the starting time of automatic plate thickness control and cutting the automatic plate thickness control when the rolling load exceeds its upper and lower threshold values. CONSTITUTION:The automatic plate thickness control AGC is turned on to commence rolling and when the plate thickness on the inlet side is enlarged after an elapsed time t0 it is modified by the operation of the AGC and when the plate thickness on the outlet side is held to a desired value, the rolling load increases. When the rolling load increases, a roll bender acts to prevent the shape of a steel strip from showing an edge wave. When the rolling load exceeds a set upper threshold value, the AGC is turned off at this time t1 (c) and the plate thickness on the outlet side comes out of a target value (b) but it is possible to prevent the shape of the steel strip from deteriorating extremely or a drawing from occurring. At a time t2 when plate thickness deviation decreases on the inlet side and the rolling load comes below the upper threshold value, the AGC is turned on again to reopen the rolling.
